Outside of that, I am really excited about the headphones. For $20 these have very good sound. Even then, it?s not enough bass to enjoy the great music. With very little hair on my head, the behind-the-neck style is more stable and comfortable. This eye wear leash works so well! I would recommend these except for the ability to use them in a loud area. First I want to say the seller sent this item fast to me, so kudos to that. I used some 3mm(?) craft foam cut into a strip and it works perfectly. This is a fantastic product. Lovely stylish trainers for a fantastic price, they look and feel awesome and go with everything.
